Whether you are an active runner managing daily knee strain, a gym enthusiast feeling the impact of heavy lifts, or simply noticing morning joint stiffness that slows down your day, your joints require targeted biological nourishment to stay smooth and flexible.
NOW® Advanced Joint Support moves beyond single-ingredient joint tablets by combining three essential joint compounds: Glucosamine Sulfate to supply the foundational building blocks of cartilage, high-purity Hyaluronic Acid to replenish natural joint fluid, and patented AprèsFlex® Boswellia serrata extract to provide fast-acting relief from everyday wear, tear, and exercise-related overexertion.
How It Works: The 3-Way Mechanism for Total Joint Comfort
Think of your joints like high-performance mechanical hinges. For a hinge to swing freely without grinding, it requires smooth rubber-like padding (cartilage), clean hydraulic oil (synovial fluid), and protection against friction and heat (inflammatory balancing). NOW Advanced Joint Support addresses all three parts simultaneously:
1. Cartilage Structure: Glucosamine Sulfate (550 mg per capsule)
Layman Explanation: Cartilage is the shock-absorbing rubber cap that coats the ends of your bones. Glucosamine acts like the individual bricks needed to build and repair that rubber cap.
Glucosamine is a naturally occurring amino sugar that your body utilizes to synthesize glycosaminoglycans (GAGs) and proteoglycans. These compounds weave together to create the firm, resilient matrix of healthy joint cartilage. By supplying stable Glucosamine Sulfate, this formula gives your joints the biological material they need to resist daily mechanical friction.
2. Internal Lubrication: Hyaluronic Acid (100 mg per capsule)
Layman Explanation: Hyaluronic acid is your body's natural lubricant—the thick fluid that prevents your joint surfaces from rubbing against each other.
Hyaluronic acid is the key constituent of synovial fluid, the specialized liquid that fills joint cavities to cushion impacts and deliver vital nutrients directly to cartilage cells (which lack their own blood supply). As we age or push our bodies during intense exercise, natural synovial fluid can degrade and thin out. Oral sodium hyaluronate helps restore the viscous, shock-absorbing qualities of synovial fluid for effortless, frictionless movement.
3. Fast Comfort & Enzyme Defense: AprèsFlex® Boswellia Extract (53 mg per capsule)
Layman Explanation: AprèsFlex acts like a molecular brake pedal, switching off the enzymes that break down joint tissue and trigger discomfort after heavy activity.
AprèsFlex® is a clinically researched, standardized extract of Boswellia serrata (Indian Frankincense gum resin) standardized to 20% AKBA (3-O-acetyl-11-keto-β-boswellic acid). Unlike standard boswellia powders that absorb poorly, AprèsFlex has enhanced bioavailability, allowing it to selectively inhibit 5-lipoxygenase (5-LOX)—a primary enzyme responsible for breaking down collagen fibers and triggering localized joint tenderness.
Clinical Science & Evidence-Based Research
Unlike generic formulas that rely on unverified proprietary blends, the active ingredients in NOW Advanced Joint Support have been evaluated in randomized, double-blind, human clinical trials:
Rapid Joint Comfort in 5 to 7 Days (AprèsFlex® Research)
In a randomized, double-blind, placebo-controlled human clinical trial published in the International Journal of Medical Sciences, subjects taking 100 mg of AprèsFlex daily experienced statistically significant improvements in joint comfort, physical function, and joint stiffness in as few as 5 days. Furthermore, serum analysis revealed significant reductions in Matrix Metalloproteinase-3 (MMP-3), an inflammatory enzyme that degrades cartilage matrix proteins.

Oral Hyaluronic Acid for Knee Lubrication and Everyday Mobility
Peer-reviewed research published in Nutrition Journal and The Scientific World Journal demonstrated that orally ingested high-molecular-weight sodium hyaluronate is absorbed into the bloodstream, distributed to connective tissues, and substantially improves knee discomfort and walking ease in active adults compared to placebo over a 12-week evaluation period.

Glucosamine Sulfate for Long-Term Joint Space Preservation
Landmark clinical trials published in The Lancet examined daily oral glucosamine sulfate supplementation over three consecutive years. Researchers confirmed that individuals receiving daily glucosamine sulfate demonstrated significant stabilization of radiographic joint space width and preservation of articular cartilage compared to progressive joint narrowing observed in the control group.

Frequently Asked Questions (FAQ)
How fast will I feel relief with NOW Advanced Joint Support?
Most customers notice positive changes in joint comfort and morning flexibility within 5 to 7 days. This rapid response is driven by the bio-enhanced AprèsFlex® Boswellia extract, which begins rebalancing inflammatory enzymes in your joint tissues quickly. Structural benefits to cartilage and synovial fluid volume from Glucosamine and Hyaluronic Acid continue to build over 4 to 8 weeks of consistent daily use.
Can I take this supplement if I have a shellfish allergy?
No. The Glucosamine Sulfate in this product is sourced from the outer shells of shrimp and crab. If you have an allergy to shellfish, you should not consume this product. We recommend looking into vegetarian joint formulas, such as UC-II undenatured collagen or standalone Boswellia and turmeric supplements.
Why is Hyaluronic Acid included in an oral joint pill?
Hyaluronic acid serves as the primary lubricating component of synovial fluid—the natural liquid that cushions joints during walking, running, and jumping. Clinical trials confirm that oral sodium hyaluronate is readily absorbed in the digestive tract, enters systemic circulation, and migrates to connective tissues to replenish joint fluid thickness and ease friction.
What makes AprèsFlex® superior to generic Boswellia serrata extracts?
Standard Boswellia powders have low bioavailability and poor gut absorption. AprèsFlex® uses a patented lipid-friendly extraction process that delivers significantly higher blood concentrations of AKBA (the primary active compound) compared to ordinary Boswellia. In clinical trials, AprèsFlex provided measurable improvements in joint comfort and flexibility in as little as 5 days.
Is NOW Advanced Joint Support safe for competitive athletes?
Yes. This product is certified by the Informed-Sport program. Each production lot is rigorously tested by an independent anti-doping laboratory (LGC) for more than 250 banned athletic substances, ensuring competitive athletes and fitness professionals can use it with complete confidence.
What is the recommended daily dosage?
Take 1 capsule twice daily, preferably with meals. Splitting the dose between morning and evening provides steady levels of hyaluronic acid and AKBA in your system throughout the day. One 60-capsule bottle supplies a full 30-day therapeutic regimen.
Can I combine this product with Collagen or Omega-3 Fish Oil?
Yes. NOW Advanced Joint Support pairs well with Omega-3 fish oil (which supports overall systemic anti-inflammatory pathways) and hydrolyzed collagen peptides or UC-II undenatured collagen (which provide structural amino acids for tendons and cartilage). There are no known adverse interactions between these joint-supportive nutrients.
